The doctrine of the Trinity is something that is absolutely fundamental to the Christian faith. First of all, the doctrine of the Trinity is a monotheistic view of God within Christianity. Monotheism is the belief in one God within a religion (unlike polytheism which believes in multiple gods). This is absolutely crucial to understand because many people of Islamic faith and other world religions believe that Christianity is a polytheistic faith. They believe this about Christianity because of the doctrine of the Trinity.
The doctrine of the Trinity states that our God is made up of three separate persons. The first person that helps make up the doctrine of the Trinity is God the Father. God the Father is the all-powerful creator of the heavens and the earth. He has always been and knows what was and is and is to come. The second person that helps make up the doctrine of the Trinity is Jesus Christ or the Son of God. Jesus Christ was begotten from God Himself. He is not a different person from the God the Father. He is God incarnate who came to earth to die for every person who has and will ever live on the earth. He was crucified and rose three days later and now sits at the right hand of God the Father. The third and final person that makes up the doctrine of the Trinity is the Holy Spirit. The Holy Spirit is the spirit of the Lord that comes upon a person when they become a believer. The Holy Spirit proceeds from the Father and Son and is once again a separate entity. The Holy Spirit descended upon the Son upon His baptism and came to believers on the day of Pentecost after the Son ascended to heaven. These are some of the distinctions between the three persons that make up the doctrine of the Trinity that Christians believe.
All three persons of the doctrine of the Trinity equals and they also all come together to form the one God of Christianity. While they form this one God of Christianity they are each equally and fully divine. God is and always has been eternally triune, however, the Trinity is not really mentioned until the ministry of Jesus Christ (the Son). However, the Holy Spirit is in the Bible long before Jesus Christ’s ministry. The Holy Spirit would come upon prophets in the Old Testament and they would perform great powers and be filled with the “Spirit of God.”
To sum up this paper on the doctrine of the Trinity why it is important I will quote Glenn Kreider notes and lecture. Dr. Kreider first said, “There is one God.” He then went on to say that, “The Father is God, the Son is God, and the Holy Spirit is God.”
He went on to say, “The Father is not the Son or the Holy Spirit, the Son is not the Father or the Holy Spirit, and the Holy Spirit is not the Father or the Son.” The doctrine of the Trinity is something that most people struggle to grasp and is something that will never be fully fathomable to any human. It is a complex doctrine that we certainly can ask God about when we reach heaven someday. However, it’s importance from a standpoint of attempting to know the persons of God and develop a more in depth, personal relationship with our God cannot be overlooked. We study the doctrine of the Trinity so that we may further our relationship and walk with the Lord. Also, we study the doctrine of the Trinity so that when we are asked a difficult question or hear someone misquote or misuse scripture about the doctrine of the Trinity, we can step in and attempt to shed light on a subject that no person can every fully comprehend.
